Culture, Not Biology, Shapes Language
There’s no language gene. There’s no innate language organ or module in the human brain dedicated to the production of grammatical language. There are no meaningful human universals when it comes to how people construct sentences to communicate with each other. Across the languages of the world (estimated to number 6,000-8,000), nouns, verbs, and objects are arranged in sentences in different ways as people express their thoughts. The powerful force behind this variability is culture.
So goes the argument in Language: The Cultural Tool, the new book I’m reading by Daniel Everett. Next week, I’ll have more to say about the book itself; this week, I want to explore how Everett’s years of living among the Pirahã Indians of Amazonian Brazil helped shape his conclusions — and why those conclusions matter.
